I have noticed that the input GPIO node is actually changing according to the position sensor.
- But it only changes after redeployment of the whole Node-RED! See video attachment.
- I have connected DI1 to output signal of the Festo position sensor and DI_GND to ground of the Festo position sensor
- I know for sure that there is voltage because my voltmeter reads 24V when triggered and 0V when not triggered.
How can I solve this problem?
